Answer:
Option (1)
Step-by-step explanation:
Fastest time recorded = 50 yards dash is 5.2 seconds.
To convert this time into the rate of miles per hour, expression to be used will be,
[tex]\frac{50\text{yd}}{5.2\text{sec}}\times \frac{3\text{ft}}{1\text{yd}}\times \frac{1\text{ mile}}{5280\text{ft}}\times \frac{60\text{sec}}{1\text{min}}\times \frac{60\text{min}}{1\text{hr}}[/tex]
By cancelling common term in the numerator and denominator in the given expression we will get the answer in miles per hour.
Therefore, Option (1) will be the correct option.
The missing factor will be 60 sec / 1 min. Then the correct option is A.
The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
Speed = Distance/Time
One of the fastest times ever recorded for the 50-yard dash in 5.2 seconds.
Then the speed (in miles per hour) will be
Then the missing factor will be
[tex]\rm \dfrac{50 \ yd}{5.2 \ sec} \times \dfrac{3\ ft}{1 \ yd} \times \dfrac{1 \ mile}{5280 \ ft} \times \dfrac{60 \ sec}{1 \ min} \times \dfrac{60 \ min}{1 \ hr}[/tex]
60 sec / 1 min
Then the correct option is A.
